Hi, 

I am using 'reserved' flag on leases to give permanent IP addresses to some clients. \
Sometimes client changes the equipment (MAC address changes) but wants to continue \
using the same IP address as before.

Man page for dhcpd states, that possible actions for hardware-address field of the \
lease object are 'examine, update'. omshell allows me to change hardware address and \
does not complain when I issue update command, bet lease object does not change, and \
when the object is reopened I see, that hardware-address did not change. I've tried \
both version 4.2.5 (CentOS 7 x64) and 4.1.1 (Centos 6 i686) with the same result.

Also, tried changing hardware-address for reserved (flags=04:00:00:00) and \
non-reserved (flags=00) lease with no success.

Is there any way to change MAC address of the reserved lease (except editing \
dhcpd.leases manually)?

P.S. I need to be able to reserve IP inside dynamic range and support for the 'on \
events', so switching to fixed-address declarations won't help.
